Fix some invalid resolved browse URLs for SWHIDs with revision anchor

The following SWHID URL:

https://archive.softwareheritage.org/swh:1:cnt:7fd7eca7869c9bffde602305395d109aee9844e8;anchor=swh:1:rev:469689991e7dbce2be4c4f618584304d91841c49;path=/data/SARS-related-CoV_ALN.fasta

gets resolved to invalid browse URL:

https://archive.softwareheritage.org/browse/revision/469689991e7dbce2be4c4f618584304d91841c49/?path=3d33572865d6703080cc6a599203481fa315bfc4/data/SARS-related-CoV_ALN.fasta

The correct browse URL should be:

https://archive.softwareheritage.org/browse/revision/469689991e7dbce2be4c4f618584304d91841c49/?path=/data/SARS-related-CoV_ALN.fasta

This must be fixed.
