Change who calls microdesc_cache_rebuild().

Previously we ensured that it would get called periodically by doing
it from inside the code that added microdescriptors.  That won't work
though: it would interfere with our code that tried to read microdescs
from disk initially.  Instead, we should consider rebuilding the cache
periodically, and on startup.
