context: rename troubled into isunstable
As we changed the meaning of unstable between the old vocabulary and the new
one, we can't reuse the unstable method name at the risk of breaking
extensions calling unstable and getting a wrong result.
Instead rename troubled into isunstable so extensions will continue to work.
The renaming is done according to
https://www.mercurial-scm.org/wiki/CEDVocabulary.
