Tests: Fix TestLibCoreArgsParser with add_positional_argument API change

Browse source 
Since we no longer populate a Vector<String> the lifetime of the strings
in all of these tests is now messed up, as the Vector<StringView> now
points to free'd memory.

We attempt to fix this for the unit tests, by saving the results in a
RAII type that should live as long as the test wants to validate some
output of the ArgParser.
