pgAdmin 4 commit: Resolve various trigger issues. Fixes #2015

Resolve various trigger issues. Fixes #2015

- Allow changing of row/statement flag
- When user update any of the parameter - trigger gets disappear from browser tree. To make it visible user has to do refresh.
- Edit Mode - 'Row level' trigger was not allowed to edit for "inline edb-spl" trigger function, even though "Row Trigger" is enabled.
- SQL was not generated properly when user change 'Row Trigger', Fires and events.
- Edit Mode - Fires and Events should be allowed to edit for "inline edb-spl" function mentioned with Code in description.
- Edit Mode - For trigger, if user edit parameters like Fires, Events, Code, Row trigger etc. then new OID is getting generated so we should fetch and return new OID in response rather then old trigger OID.
