[codeInsight] IDEA-201714 Missing "fix all" for "Redundant throws clause"

Redundant throws exception inspetction used to report both the redundant
exceptions in the throws list and @throws tags in the javadoc. It was
not convenient since the same problem got reported twice. This patch
changes this behaviour, no @throws tags is reported as redundant. If
there are redundant @throws tags they get removed when its corresponding
throws declarations is being removed. The redundant @throws tags are
detected like this:

1. If there is only one throws declaration in the throws list of a
method then all the @throws tags get removed.
2. A @throws tag is considered related to the throws declaration that is
being removed if it is the exact match with the throws declaration or if
it is a subclass of it and there are no exact matches for the @throws
tag in the throws list.
3. If there are duplicates in the throws list then when one of the
duplicates is getting removed then all the related @throws tags are
considered related to that copy leaving the other duplicates without any
related @throws tag in the javadoc.
