PHP 8.0 | PSR2/FunctionCallSignature: support named parameters

The `File::findEndOfStatement()` method regards a `T_COLON` as the end of a statement, while for function call arguments using named parameters, the colon is part of the parameter name declaration and should be disregarded when determining the end of the statement.

Fixed now.

Includes unit tests.
