In cases where MuGirl muons are also reconstructed by STACO, they can have an MS track particle, the one used by STACO, associated to them.
Given that this MS track was not used in reconstructing the muon, this can be misleading: this fix ensures that MuGirl muons never have an associated MS track.
Since the MCP tools use the ME track, this change should be transparent for the vast majority of analyzers.
The MS-only extrapolated track, only used by experts for debugging, is retained.

Needed to respect ToolHandle constness rules.

Don't try to touch TileBeamInfoProvider here
(was only changing OutputLevel).

Add missing link dependency on AthViews.

Another step towards deprecating DataHandle: remove all methods to retrieve
the referenced object as non-const.

  * Extra hard-coded chains in HLTConfigSvc.cxx
  * Unchecked status code bug fix in TrigSignatureMoniMT.cxx
  * Addition of basic TDT printing in TrigEDMChecker.cxx
  * Revamp of checkESD.py

- Only create worker directory if it does not exist yet
- Delete worker directory if it did exist already. This is required as
  the THistSvc crashes on `io_reinitialize` in case a ROOT histogram
  file already exists.
