DevelopmentCodeFragment does not catch fully qualified functions

[bkdotcom]

• PHPMD version: 2.9.1
• PHP Version:7.4.12
• Installation type: composer
• Operating System / Distribution & Version: OSX 10.14.6

Current Behavior

\print_r not caught

Expected Behavior

The method foo::bar() calls the typical debug function print_r() which is mostly only used during development.

Steps To Reproduce:

function bar($baz)
{
  \print_r($baz);    // not caught by DevelopmentCodeFragment rule
  print_r($baz);    // caught by DevelopmentCodeFragment rule
}

Confirmed. Actually, this rule doesn't work when there is an active namespace so I actually never had it working in my projects. But allowing starting \ in function names would be a good start.
