remove unit test in RecoTauTag/HLTProducers

[missirol]

PR description:

This PR removes a unit test introduced in #35640 (blame it on @missirol).
Policy is not to run the full HLT menu (+customisations) to test individual modules; see discussion in #35863.
A much simpler unit test for the module in question could be designed in the future.

please test

Thanks @missirol
This construct of a test is too brittle and not robust, as the customisation may break any time the underlying menu is changed, leading to a failing test.

merge

• Tests are still running, but ok: this PR just removes a \test area, and we really don't expect possible issues besides removing the currently failing unit test. Merging it now will allow having the fix included in the 1100 IB, on which we can then base the CMSSW_12_1_0_pre5 pre-release if there are no further issues that pop up.
