Fix PhraseMatcher to work with new Matcher

[sadovnychyi]

Motivation and Context

#613

How Has This Been Tested?

PhraseMatcher wasn't tested at all, I've added a basic test for it.

Types of changes

• Bug fix (non-breaking change fixing an issue)
• New feature (non-breaking change adding functionality to spaCy)
• Breaking change (fix or feature causing change to spaCy's existing functionality)
• Documentation (Addition to documentation of spaCy)

Checklist:

• My code follows spaCy's code style. (it's coming soon though)
• My change requires a change to spaCy's documentation.
• I have updated the documentation accordingly.
• I have added tests to cover my changes.
• All new and existing tests passed.

P.S. Would be cool to have test script using makefile or something to easily run them. I had to look into travis scripts to learn how to do it.
