BUG: Form errors are not shown after validation

[atarkowska]

Each form has certain level of validation that has to be presented for the user when submitted data are not correct or missed. That problem refer to:

• field are mandatory
• field tested for unique value (like username, email, etc)
• field validated for specific values.

The test works as expected with build OMERO-merge-green/112 but there are the following incorrect messages:

• "This username already exist" to "This username already exists"
• "User must to be a member of at least one group." to "User must be a member of at least one group."
• "Password must be at least 3 letters long" to "Password must be at least 3 characters long"

• "User must to be a member of at least one group." to "User must be a member of at least one group."
• "Password must be at least 3 letters long" to "Password must be at least 3 characters long"
