Bump phan/phan from 2.2.6 to 2.2.7

[dependabot-preview]

Bumps phan/phan from 2.2.6 to 2.2.7.

Changelog

Sourced from phan/phan's changelog.

Jul 27 2019, Phan 2.2.7

New features(CLI, Configs):

• Include columns with most (but not all) occurrences of PhanSyntaxError
  (inferred using the polyfill - these may be incorrect a small fraction of the time)

  When the error is from the native php-ast parser, this is a best guess at the column.

  hide_issue_column can be used to remove the column from issue messages.

• Add --absolute-path-issue-messages to emit absolute paths instead of relative paths for the file of an issue. (#1640)
  Note that this does not affect files within the issue message.

• Properly render the progress bar when Phan runs with multiple processes (#2928)

• Add an HTML output mode to generate an unstyled HTML fragment.
  Example CSS styles can be generated with internal/dump_html_styles.php

• Add a light color scheme for white backgrounds.

New features(Analysis):

• Fix failure to infer real types when an invoked function or method had a phpdoc @return in addition to the real type.
• Infer union type from all classes that an instance method could possibly be, not just the first type seen in the expression's union type. (#2988)
• Preserve remaining real union types after negation of instanceof checks (e.g. to check for redundant conditions).
• Warn about throwing from __toString() in php versions prior to php 7.4. (#2805)
• Emit PhanTypeArraySuspiciousNull for code such as null['foo'] (#2965)
• If a property with no phpdoc type has a default of an empty array, assume that it's type can be any array (when reading it) until the first assignment is seen.
• Attempt to analyze modifying dynamic properties by reference (e.g. $var->$prop when $prop is a variable with a known string)
• For undeclared variables in the global scope, emit PhanUndeclaredGlobalVariable instead of PhanUndeclaredVariable to distinguish those from undeclared variables within functions/methods. (#1652)
• Emit PhanCompatibleSyntaxNotice for notices such as the deprecated (real) cast in php 7.4, when the real parser is used (#3012)

Language Server/Daemon mode:

• When PhanSyntaxError is emitted, make the start of the error range
  the column of the error instead of the start of the line.

Plugins:

• Add EmptyStatementListPlugin to warn about empty statement lists involving if/elseif statements, try statements, and loops.
• Properly warn about redundant @return annotations followed by other annotation lines in PHPDocRedundantPlugin.

Bug fixes:

• Treat Foo::class as a reference to the class/interface/trait Foo (#2945)
• Fix crash for (real) cast in php 7.4. (#3012)
• Work around crash due to deprecation notices in composer dependencies in php 7.4
