==== What is the problem?
When creating a global block with autoblock enabled on the non-central wiki and the user you are trying to block has several entries in the `cuci_user` table, I get the below exception:
```
[cdc2d3f26403275f14dd3384] /wiki/Special:GlobalBlock Wikimedia\Assert\PreconditionException: Expected MediaWiki\User\UserIdentityValue to belong to the local wiki, but it belongs to 'commonswiki'

==== Steps to reproduce problem
# Setup a wiki with several wikis connected with CentralAuth, GlobalBlocking and CheckUser and config `$wgGlobalBlockingEnableAutoblocks = true; $wgAutoCreateTempUser['enabled'] = true;`
# Login as a user and make edits on several different wikis
# Login as a steward on one of the wikis which is not the central wiki (i.e. not the value of `$wgCentralAuthLoginWiki`)
# Go to Special:GlobalBlock, enter the user from step 2, check "Automatically globally block the last IP address..." (it is by default) and submit
**Expected behaviour:** Global block is created.
**Observed behaviour:** Above exception.
