Bug 16770: Remove wrong caching of 3 subroutines in C4::Lancuages

Bug 16770: Remove wrong caching of 3 subroutines in C4::Lancuages

ooking at this code, you might think these subroutines are cached, but
actually they are not.

The eval surrounding the code hides a bug, if you remove it, you will
get:
  Invalid memcached argument (expected a hash)

Test plan:
Do not apply this patch and confirm that the code does not work
