Do not use spaces in 'Copy position' result in Assembly Browser.

Assembly Browser adds spaces to the "Copy position" result as a group separator for big numbers.
 
This causes some tests to fail when running on the high-resolution screens with a position > 1000 in the center.
 
UGENE should not "randomly" format position and should use either a standard math notation (as expected by tests) or use the OS default number formatter for the active user locale.
 
In my opinion, a simpler and more flexible fix should be to avoid any formatting, so the result can be copied/pasted by using other tools/forms.
