Entry import should generate citation key

[koppor]

When importing https://dx.doi.org/10.18417/emisa.4.1.1, the citation key is not generated, but used. That should be changed

Note: A few years ago, there was a strong discussion on that. This discussion should be found.

Similar to JabRef#895 ?
Also similar to JabRef#8354 (comment) if it comes to running clean-up ops.

@koppor Do you have the Option "Generate new key for imported entries" under preferences -> import and export activated?

[k3KAW8Pnf7mkmdSMPHz27]

@Siedlerchr I think it has a different code path. Unless I screwed up, that preference did nothing when I tried this import option

[Siedlerchr]

@k3KAW8Pnf7mkmdSMPHz27 you are right. I dug a bit into the code.

The code from the NewEntryTypeViewModel should be copied/reused to make it consistent. I'm preparing a PR
