Restoring a record does not take into account ActiveRecord validations

[spint]

Since version 2.1.4, (uniqueness) validations checks only non-deleted records.
However, restoring a record that violates a Rails uniqueness constraint passes without an error.
Shouldn't the validations be considered before saving the restored record to the database?

Looks to be the same as #319 and #333 is a proposed fix.

For now, you can enforce the uniqueness at the database by updating your indexes. When you try to restore and it violates the database index, a mysql error should be raised.
