Update monitors on refresh

[unkrich]

Problem

Monitors are created on the initial run via a SchemaCollectorJob https://github.com/monosidev/monosi/blob/master/src/server/handlers/datasources.py#L55

After this, if new tables, columns, or other entities are introduced, we do not automatically monitor them and we should consider doing so.

Solution

The simplest solution may be to keep this job running and not remove it as in line https://github.com/monosidev/monosi/blob/master/src/server/handlers/datasources.py#L69

This is a shortsighted but temporary possible solution is to simply delete this line (mostly made possible due to db constraints to make sure duplicate monitors aren't created).
