fix: Split multiple slashes tests into three

- `testPathWithMultipleSlashes()` modified to have a path with multiple slashes only in the middle of the path.
- Renames `testProperlyTrimsLeadingSlashesToPreventXSS()` to `testGetPathNormalizesMultipleLeadingSlashesToSingleSlashToPreventXSS()`, and has it assert only against results of `getPath()`; on completion, it returns an associative array with the expected URI string and the URI instance.
- Adds `testStringRepresentationWithMultipleSlashes()`; depends on `testGetPathNormalizesMultipleLeadingSlashesToSingleSlashToPreventXSS()`, and asserts that the string representation is identical to the original URI string.
