Correct type check for the onBlur handler for SQLEditor

[shelldandy]

Otherwise type checking fails when attempting to use the prop as intended:

hi @shelldandy , could you please explain the use-case where you need this? i mean, onBlur already calls onChange, so the parent component will be notified about the change (maybe it should not call onChange, but that ship has probably sailed already 😄 )

[shelldandy]

For some reason on the VariableQueryEditor page the Run Query button on the page sometimes it's not on sync with the rest of the page (probably because on earlier grafana versions that button wasn't there)

So to fix that issue what we've been doing on enterprise Datasources is to add an onBlur event to force a model update of the onChange function so hitting the button works as intended

LGTM 👍
