new backend: remove all contacts never ends
Step to reproduce:
Select all contacts, then delete. The UI is stuck on the popup, CPU is high and never ends:
output from logs:
Creation of org.nemomobile.contacts.sqlite engine failed.
The 'mergePresenceChanges' option has not been configured - presence changes will only be reported via ContactManagerEngine::contactsPresenceChanged()
"Query failed: unable to open database file Unable to execute statement\n\n PRAGMA journal_mode = WAL;"
"Failed to configure contacts database: "
"Unable to open asynchronous engine database connection"
