The check for `Track::seedRef()` availability in MultiTrackValidator, added in #14248, was not sufficient. This omission leads to an exception from missing product in the MTV standalone mode ([SWGuideMultiTrackValidator#cmsDriver_MTV_alone_i_e_standalo](https://twiki.cern.ch/twiki/bin/view/CMSPublic/SWGuideMultiTrackValidator#cmsDriver_MTV_alone_i_e_standalo)). Requiring explicitly the availability of the seed product fixes the exception. Thanks to @username_2 for reporting the bug.

Tested in CMSSW_8_1_0_pre6, no changes expected in standard workflows.

@username_3 is it possible to fit also this in pre8? It would be useful (with another PR that I am testing now) to fix the validation for the phase2 tracking.. We just discover the issue today.

@davidlange6 this seems to be a one-line bug fix, would be nice to put in pre8.

@dmitrijus, @vanbesien please review and sign if possible (I realize it's short notice, but it seems to be a straightforward change).
