c51d544932a666851c39f79a517e2e0a1e783b05 [wip] Ensure there are no duplicated script_pubkeys in sqlite (Alekos Filini)
Pull request description:
### Description
Add a `UNIQUE` constraint on the script_pubkeys table so that it doesn't grow constantly when caching new addresses.
Fixes#801
### Notes to the reviewers
Adding it to the 0.25 milestone since it's just a bugfix.
Still in draft because I need to add extra migration queries to clean up existing dbs.
