Optimize USER_NAME_PATTERN string and its usage

The following issues from [1] are addressed by this change:
1. common pattern part was extracted
2. USER_NAME_PATTERN string is used to indicate that account
couldn't have been created as it is not compliant with it
3. number of lines was reduced in USER_NAME_PATTERN by combining
relevant characters together

In addition:
USER_NAME_PATTERN_LAST is derived from USER_NAME_PATTERN_FIRST
as they are equal.
