Get an error during snapshot if a .gitignored directory is under a results resource

[jfischer]

Example: Have .DS_Store under the workspace's main .gitignore. The "report" results resource has these directories due to .png files it contains. When the code tries to move the files under snapshots and add them to git, get the following error:

dws snapshot -m 'Initial version of reporting' 2020-APRIL-30
The following paths are ignored by one of your .gitignore files:
reports/snapshots/jf-mbp-2017-2020-APRIL-30/.DS_Store
Use -f if you really want to add them.


The following paths are ignored by one of your .gitignore files:
reports/snapshots/jf-mbp-2017-2020-APRIL-30/.DS_Store
Use -f if you really want to add them.
