Fix inconsistent metadata after healing (#14125)

Browse Source

When calculating signatures empty part ETags were not discarded, leading 
to a different signature compared to freshly created ones.

Furthermore when inconsistent entries, with zero version ID, with the same 
mod times but different signatures, the one with the lowest signature would 
be picked for quorum check. Since this is 50/50, we fall back to a simple 
quorum count on all signatures.

Each of these fixes by themselves will lead to quorum. Tests were added 
for regressions and expected outcomes.
