- Make "Back to all challenges" button translatable
- Allow some flexibility for the line "#_of_gems gem_icon Prize" - this
is made following the practices with linkstart/linkend implementation
- prize "string" is left as is because used as a placeholder
- code comment "prize" had to be moved 1 line up - before the p (as no
room for it is left inside the p) which however seems OK to me, because
the comments above and below has been made the same way before
* move challenge test to separate file
* adjust wording of popover text
* prevent refunding gems for tavern challenges
* adjust ui of challenge creation page
* fix bug in cancel function
* adjust wording of delete confirmation message

It would be great if we could have "%number_of% Participants" instead of just "Participants" in the source language so that we could translate it as "участников: %number_of%" which is the only correct way to translate it into Russian without grammatical mistakes. (This example is from Challenges tab.)"
