Simon Frei cb0f4ce55a lib/model: Don't stop folder if out of disk space (fixes #2370) (#5099)
This removes the out of disk space check from CheckHealth. The disk space is now
only checked if there are files to pull, in which case pulling those files is
stopped, but everything else (dirs, links, deletes) keeps running -> can recover
disk space through pulling.
