Bump to go 1.14

Fix failing tests that are checking the error string returned from the stdlib. In go1.14 the formatting changed to https://github.com/golang/go/blob/release-branch.go1.14/src/net/url/url.go#L29 from https://github.com/golang/go/blob/release-branch.go1.13/src/net/url/url.go#L29. Since it's using %q now the url is wrapped with " ".

Also since we updated our go.mod to use go1.14 GoLand 2019.3.2 doesn't mange to load the vendor directory since it doesn't understand the new logic just yet. The GoLand EAP understand it perfectly fine, however note that there is a known issue https://youtrack.jetbrains.com/issue/GO-8860 that doesn't resolve interfaces.
