Obsolete readersAboutToBeInvalidated()

There is not anymore any "reader" for the content and index providers.
They were removed in commit 829f9dec6bff57e8b3f1afdc982778a9d573174f
in 5.11 branch, when introducing the index
and contents caches in qhc file.

Also currently readersAboutToBeInvalidated() wasn't used anymore anywhere,
so this patch just removes the emission of this signal.
