test-largefiles: demonstrate problems with renaming and reverting a directory

These things were uncovered looking at issue5738.

First, if the destination directory exists under .hglf, the source is moved
under the destination instead of renaming the last component for `hg mv srcdir
dstdir`.  This is extra confusing, because it occurs even if the user visible
destination (i.e. the path _not_ under .hglf) does not exist.

Additionally, when a largefile is forgotten via revert, any modifications end up
getting clobbered.  For normal files, the forgotten file is left unchanged, as
shown by test-import.t.  The forget command on a largefile will correctly leave
the file unmodified.
