Change the warning when no margin catalog to be more accurate ``Results may be incomplete''

[nevencaplar]

Change the wording of the warning when right catalog margin has not been supplied from:

Right catalog does not have a margin cache. Results may be inaccurate

to
Right catalog does not have a margin cache. Results may be incomplete or inaccurate. (this maybe should be refactored further - I want the message to be more informative)
