Bug 1269365, part 1 - Swap fallible and infallible TArray ParamTraits. r=froydnj

This should not change the behavior, because fallible_t is passed to
the array methods.

Rename from InfallibleTArray to nsTArray, because that is more usual.

Remove unnecessary spaces from some template definitions.
