Ben Wiederhake f890b70eae Tests: Prefer TRY_OR_FAIL() and MUST() over EXPECT(!.is_error()) 
Note that in some cases (in particular SQL::Result and PDFErrorOr),
there is no Formatter defined for the error type, hence TRY_OR_FAIL
cannot work as-is. Furthermore, this commit leaves untouched the places
where MUST could be replaced by TRY_OR_FAIL.
