publishDir with trailing slash creates trivial revision

[drernie]

A last interesting finding was that a single file in one of my nextflow processes seemed to be driving a behavior of creating a second almost empty quilt revision for a single nextflow run.

The only difference about that process was that it had a “publishDir” directive with a trailing slash while all other processes do not...

When I removed the trailing slash for that one process then the system went back to making only 1 revision of the quilt package with all the expected files.
