Invalid project key: *, only alphanumeric and uppercase values are allowed

Users may have issues when creating reviews and the following message will appear in the browser after pressing "Create Review":

Invalid project key: *, only alphanumeric and uppercase values are allowed

Problem description

The following scenario have to occur:

1. Crucible (pre 3.10 version) instance
2. Creating projects: proja (lower-case)
3. User A viewing this project: proja
4. Project: proja is deleted (bug: proja stays in users history)
5. User A viewing less then 5 existing project in the whole history of Crucible: projb, projc, so now the history of visited projects for user A is: proja, projb, projc
6. Crucible is upgraded to 3.10 (project keys are upgraded, renamed project keys are deleted from user history), now the project history for user A is: proja
7. User A goes to Crucible and hits the Create Review button, the suggested project will be taken from project history for user A which is the non-existing, invalid project: proja

Workaround

Delete from user history all invalid projects:

delete from cru_recently_visited where cru_item_type in ('atlassian-project','atlassian-review','atlassian-snippet') and UPPER(cru_entity_id) != cru_entity_id

or delete all user history:

delete from cru_recently_visited where cru_item_type in ('atlassian-project','atlassian-review','atlassian-snippet')

or delete from user history all non-existing projects,

//todo

or ask user to visit an existing project which would change user's view project history: the last visited invalid/non-existing project to a valid existing project
