ConvertToMD should not need a goniometer if UB matrix is specified on a workspace

[Alex Buts]

this is requested by Diffraction peoples

Currently it does not allow to run if no goniometer is defined. Diffraction peoples say that UB matrix is all what they need.

Goniometer in this case should be set to 0 angle (unit matrix)

refs #8044 this should fix it

Trivial ticket implemented on the diffraction people request. The script below should fail on old Mantid but just print warning on the new one.

Very careful tester can try ConvertToDiffractionMDWorkspace v2 (recent version) against V1 (old version) where v2 should fail for old version of Mantid and run after this ticket. V1 would run in all versions.
