Configured to use wrong location for contacts in SailFish 4.5.0.21

[threepistons]

• Given: reasonably recent installation of Sailfish 4.5.0.21 on Xperia 10 III, latest SailfishConnect from OpenRepos via Storeman, and KDE Connect as shipped with Debian Bookworm (sorry, I can't find an "About" dialog with a version number in it).
• When I: use Fingerterm on the Xperia to launch SailfishConnect.
• I get: messages about the contact database not being opened, see logs below.
• I expect: the contact database to be opened successfully.

The contact database is at /home/defaultuser/.local/share/system/Contacts/qtcontacts-sqlite but SailfishConnect expects it at /home/nemo/.local/share/system/Contacts/qtcontacts-sqlite/contacts.db.

Seems to be hardcoded in

harbour-sailfishconnect/pluginscommon/contactsmanager.cpp

Line 32 in e586d06

"/home/nemo/.local/share/system/Contacts/qtcontacts-sqlite/contacts.db");

https://stackoverflow.com/a/26696759 gives an idea of how set a string to be the logged-in user's $HOME. I don't speak C++, but if we were in Puppet, I'd use string interpolation or concatenation to accommodate the new multiple-user Sailfish.

// Magic to get a string called homedir
// I'm not sure that the `const char` in the Stack Overflow will concatenate with a string
// so I'm disinclined to paste that example code here.

static QString QTCONTACTS_SQLITE_STORE = QStringLiteral(
    homedir + "/.local/share/system/Contacts/qtcontacts-sqlite/contacts.db");
// https://cplusplus.com/reference/string/string/operator+/ says that + is the correct operator

IIRC there are some standard paths provided by Qt already, QStandardPaths::HomeLocation or maybe QStandardPaths::GenericDataLocation as a shortcut.

The contacts database is no longer used by Sailfish OS: https://forum.sailfishos.org/t/4-0-1-45-non-jailed-contacts-sqlite-database-no-longer-updated/4724
The whole contacts feature have to be rewritten.
