Squiz/EmbeddedPhp: add tests safeguarding that single line embedded PHP blocks are never ignored

The exception conditions for the first/last tag set only apply to multi-line PHP blocks and PHP blocks without a closing tag.
Single-line embedded PHP with a complete set of tags should not be affected.

This is already handled correctly. This commit just adds tests to safeguard this.
