HideDiagnostics configuration not honored

[cherrymui]

If the -hidediag flag is not specified on the command line, it should honer the HideDiagnostics setting in the config file. Currently it is not:

$ cat ~/Library/Application\ Support/acme-lsp/config.toml | grep HideDiagnostics
HideDiagnostics = true
$ acme-lsp -showconfig | grep HideDiagnostics
HideDiagnostics = false

This is because it is overwritten by the flag's default value. The following patch fixes it
