PSUseConsistentIndentation: Check indentation of lines where first token is a LParen not followed by comment or new line (#1995)

* Check a line starting with LParen for correct indentation, even if that LParen doesn't impact the indentation level

* Fix typo in test utility for the UseConsistentIndentation tests

* Add tests to ensure formatting is still checked when LParen is the first token on a line, followed by a non-newline, non-comment
