Using context for blocks with block_token causes a warning when saving blocks

Problem/Motivation

Saving blocks using the context module causes warnings:

Warning: Trying to access array offset on value of type null in block_token_form_block_form_alter() (line 178 of /www/dev/ato1-008/web/modules/contrib/block_token/block_token.module)

Warning: Undefined array key "id" in block_token_form_block_form_alter() (line 178 of /www/dev/ato1-008/web/modules/contrib/block_token/block_token.module)

Steps to reproduce

Install context. Create block and go to edit any block using context editor. Check the logs.

Proposed resolution

There was a simular issue in antibot using context but a fix was posted. I think they check for the presence of the key.
