[Editor]: Search in the whole catalog from any dashboard

[cmoinier]

Description

This PR makes sure the search through the search header is done throughout the whole catalog, from any dashboard. For instance, the user can find records that they don't own if they start a search from "My records" dashboard.
It also clarifies the search state process, to make sure the states for "myRecords" and "allRecords" stay distinct and are not reinitialized at every render.

Thanks, @cmoinier ! It works really well. I just saw some issues related to the search filters I've merged. I'll take a look at this. => Should now be fixed in #1065

Regarding the code, I left some comments for things I think we should try to improve.

Thanks also for adding back the search to the draft page. We might still get rid of one of the gray separator bars under the search here and maybe move the title up? I can't find the mockups for it.
