'on-column-filter' event emitted for every column that has an initial 'filterValue'

• Bug

Specs

What version are you using?

Latest 2.15.3

What browser?

FF, Chrome

Expected Behavior

What did you expect to happen?

I expected the 'on-column-filter' even to be emitted once when the table loads, with all of the values from any initial column filterValues.

Actual Behavior

What actually happened?

'on-column-filter' is called once for each column that has an initial filterValue.

We are using the 'on-column-filter' event to trigger an API call to fetch data, so having the event triggered for every filterValue passed in to the column definition means our API is called once for each filterValue. I'm not sure how to discern when the 'on-column-filter' events are coming from the initial table creation filterValues, and when they are coming from user provided input, so I can't find a clear way to not call the API on certain triggers of 'on-column-filter'.

Steps to Reproduce the Problem

Please detail your steps here

1. Create a table with multiple columns, and have filterValues in at least two column definitions
2. Log the number of emitted 'on-column-filter' events

@skray thank you for detailed report on this bug. v2.16 should fix this for you.

I am on 2.16.0 and this behaviour exists for me still. I also pass in a default filter on a column and both on-column-filter and on-per-page-change are called when the component mounts.

I am using 2.16.0. But still this behaviour exists.
