Revert "escapeds changes"

While this change doesn't break the creation, it does break
idempotency. This change will convert '*.*' to '`*`.*' which is
functionally the same, however when the user_mod() function looks up
the current privileges with privileges_get() it will read '*.*'

Since '*.*' != '`*`.*' it will go through the process of updating the
privleges always resulting in a 'changed' result.

This reverts commit db9ab9b262.
