Improved Subgraph Events Sorting

[rdig]

This PR introduces events sorting on the subgraph side, by adding a timestamp prop on all event entities on that are coming from the subgraph, so that we can pass query selection fields like orderBy and orderDirection

Besides the above, I've also refactored the ColonyEvents component (it actually started this) to properly have pagination (before this, we would just fetch the first 100 events, then split them up locally)

Note that we cannot do the same for the ColonyActions component due to the way we are combining 4 data streams into one, and not always symmetrical (this will become a problem once a colony surpasses 1000 combined actions)

Since sorting is now done directly, prior to the data reaching our data, I also removed the sortSubgraphEventByIndex util, as it was no longer required

Testing note

Since this is using an update version of the subgraph, make sure to run npm run provision prior to testing this

This is a nice improvement to the SubGraph data and handling sorting.

I did notice that the 'Load more' button still appears on the last item when there are no more results.

Sorting looks to be working much better.

Two things about dates in the local dev environment to keep in mind:

• account for them
• but don't trust them

They can and are manipulated either by us directly or by various services we have running in the background

Very good!

It's working as expected from what I could see! Well done
