Blocks inserted with the Side Inserter don't increment the usage count

[pento]

Issue Overview

#4953 added the side inserter with frequent block shortcuts, which is super cool.

Unfortunately, adding blocks using this new functionality doesn't increment the relevant counter in state.preferences.insertUsage, so the frequent block shortcuts don't change.

Steps to Reproduce

1. Open a new post.
2. Click in the default paragraph.
3. Observer the state of state.preferences.insertUsage.
4. Click a frequently used block, or a block from the inserter.

Expected Behaviour

The state.preferences.insertUsage counter should increment for the block that you just switched to, so that the frequently used blocks list rearranges itself correctly.
