Supress all editor event based errors

[kumarharsh]

Sometimes, the gql plugin starts throwing these errors which keeps starting up the output terminal:

[Error - 12:24:29 AM] Request textDocument/hover failed. Message: Request textDocument/hover failed with message: Cannot read property 'getText' of undefined Code: -32603

Mostly, this happens after a computer sleep and any non-gql code when hovered starts throwing this error. These kind of errors need to be handled gracefully and not cause confusion.
