`Uncaught Error: Connection is closed.` on invalid enum field in config

[alex35mil]

Sometimes when I type not fast enough in diagnostics.tools field (e.g. bsb, merl) I get hard error Uncaught Error: Connection is closed..

Something to investigate.

Looks like it's because the atom-languageclient watches the plugin config changes very fast, and read some uncompleted input.

Sorry that I didn't look your error stack before, the stack contains some from ide-flowtype, not ide-reason, it's strange, but I didn't find some clue after a quick look at ide-flowtype's source, I guess it's still caused by atom-languageclient.

Yeah, I checked ide-flowtype sources as well and it doesn't seem related to their FlowLanguageClient class.
