Fix the option File and Package of Dev::UnitTest::Run

[bschmalhofer]

It looks like the changes for #2267 broke commands like:

• bin/otobo.Console.pl Dev::UnitTest::Run --Test scripts/test/Znuny4OTOBOEscalationSuspend/EscalationSuspend.t
• bin/otobo.Console.pl Dev::UnitTest::Run --package ITSMConfigurationManagement

The list of test files was empty.

Apparently there in error with nested loops in:

247         # check if only some tests are requested
248         if (@ExecuteTestPatterns) {
249             @Files = grep {
250                 any {m/\/\Q$_\E\.t$/smx} @ExecuteTestPatterns
251             } @Files;
252         }

the grepand anyloop are nested, so the topic $_ was matched against itself, but with ".t" appended.

PR is merged. A quick manual test looked fine. Closing this issue.
