Fixes #7908 - normalize mac before host get saved

For some reason we save host without running valdiations when we import
attributes from facts. Therefore we have to take care of mac
normalization by ourselves. We have to normalize it just after setting
new value because save can occure anytime.
Fixes #8456 - normalize addresses only if mac is being set
fixes #8457 - auto complete search clear btn is now positioned correctly

in non index pages which uses auto complete (e.g. filters) the clear

Fixes #6765 - correct wrong validation on media name

Regex used for validation was wrong, raising error on multiple white spaces instead of on trailing white space.
Trailing white space is stripped anyways by StripWhitespace concern before validation.
Original bug was concerning " " passing validation. However, that is not a single white space but rather quotes with a
space between them; while not useful, it is a valid name. (The quotes are escaped in the db)
