Bug 11401: (followup) make tests run on absent deps

The current code breaks if a dependency is missing. The evals are
rearranged so there's no error on missing dependency.

To reproduce:
- Have a dependency for t/NorwegianPatronDB.t removed
- Run
  $ prove t/NorwegianPatronDB.t
=> FAIL: You see an error similar to this (may vary depending on the lib you removed):

t/NorwegianPatronDB.t .. You tried to plan twice at t/NorwegianPatronDB.t line 37.

- Apply the patch
- Run
  $ prove t/NorwegianPatronDB.t
=> SUCCESS: Tests are skipped on missing lib
