Include default argument value when argument has no type

[sforward]

This PR fixes handling default argument values when the argument has no type specified. In that case the default value is currently omitted.

This notation was already working as expected:

@method void myMethod(string $arg = '')

With this PR this is also correctly handled:

@method void myMethod($arg = '')
