When the UI disconnects, we can throw away any server-side remote
datastores we created in response to calls from the UI, and we *must*
drop everything in extraconfigdata or it will taint any future
operations.
Dropping extraconfigdata upon disconnect fixes taskhash mismatch errors
when running devtool.DevtoolTests.test_devtool_update_recipe_local_files
within oe-selftest with BB_SERVER_TIMEOUT=100 in OpenEmbedded.
