scheibelp 1e69d9d1a9 Override partial installs by default - part three (#4331)
* During install, remove prior unfinished installs

If a user performs an installation which fails, in some cases the
install prefix is still present, and the stage path may also be
present. With this commit, unless the user specifies
'--keep-prefix', installs are guaranteed to begin with a clean
slate. The database is used to decide whether an install finished,
since a database record is not added until the end of the install
process.

* test updates

* repair_partial uses keep_prefix and keep_stage

* use of mock stage object to ensure that stage is destroyed when it should be destroyed (and otherwise not)

* add --restage option to 'install' command; when this option is not set, the default is to reuse a stage if it is found.
