libtracker-miner: Emit ::file-updated on file extension changes

We have no access to past/current GFileInfos, so detect changes in
file extensions to handle the cases where a change of filename
results in the file having a different mimetype.

In these cases, ::file-updated should be emitted, so it gets the
right rdf:types as per its new mimetype.
