To correctly perform its testing function,
test-dump-untracked-cache should not change the state of the
untracked cache in the index.
As a previous patch makes read_index_from() change the state of
the untracked cache and as test-dump-untracked-cache indirectly
calls this function, we need a mechanism to prevent
read_index_from() from changing the untracked cache state when
it's called from test-dump-untracked-cache.
