Bug 1308317 - Part 6: Remove nsSupportsArray::GetIndexOfStartingAt. r=froydnj

Browse Source 
This removes the scriptable method |GetIndexOfStartingAt| which is unused in
our codebase and turns up no references in the plugins repo. This allows to
remove the non-scriptable |IndexOfStartingAt| which is folded into |IndexOf|.
