1)Add file to Synapse (lets say it is under syn123)
2) addnew versions of the file such that there are 2 versions of same file.
These files now have versionNumbers 1 and 2
3) Add another file to Synapse that uses syn123.2 in provenance
4) Delete syn123.2
5) Upload a new version to syn123 which now has the same versionNumber 2
Provenance is now incorrect!
