[ticket/11548] Run array_map on complete error array and not just colour_error

Up to now the array_map() that turns error messages into the localized output
was only ran if the group's color was set. With this patch it'll run the
array_map() on the complete error array if it's not empty.

[ticket/11548] Fix incorrect usage of array_map on acp groups page

The array_map was only ran on small parts of the actual error array instead
of the whole one. This resulted in the output of the language variables' names
rather than their actual value.
