libdaemon: fix misleading "WARNING: Ignoring unsupported value for expected." when communicating with daemon

When we're trying to search for certain tree node
in daemon's reply, we default to a blank string ""
if the node is not found. This happens during lvmetad
initialization.

However, when the default blank string is used, we
can't use dm_config_find_str at the same time - the
dm_config_find_str_allow_empty should be used instead.
Otherwise a a warning message:

  "WARNING: Ignoring unsupported value for ..."

is issued.
