Cannot download 2 files with same sdhash

The Issue

Lower priority since this shouldn't happen in most cases (.i.e. claim is created manually)

Example: lbry://doit2 / lbry://doitlive

Start in lbrynet/extras/daemon/storage.py around _save_claims at line 649 and _save_content_claim at line 715, using the reported two-file same-sdhash example and traceback. Trace how the two claim IDs are handled during download and add a regression test showing both files can be downloaded without the mismatching-claim-ids error.
