Rename Two Test Files (#2459)

* Rename Two Test Files

When I run unit tests only for Reader/Xlsx, phpunit is issuing a deprecation message because the names of 2 files have an extra dot in them and thus don't match the class name in the file. I do not see these warnings when I run the entire test suite.

* Remove Phpstan Annotations

It was a bit difficult to handle a cast from mixed to string.

* Fix Same Phpstan Problem in One Other Test

This is the only other test case that tries to cast mixed to string.
