attempt to install broken cumulative patch is correctly rejected but previously installed one-offs are partially invalidated (at least one-offs which add misc files)

see test CumulativePatchingScenariosTestCase#testOneOffInvalidCumulativePatch
it installs one-off that adds misc file then installs one-off that adds module
and then tries to install broken CP, CP is rejected but misc file added by first one-off doesn't exist
