Task version sorting goes wrong for scmultiplex task

[jluethi]

The task version sorting needed to display the most recent task and also to decide which tasks can be updated goes wrong on the FMI server running fractal web 1.16.0, fractal-server 2.13.1 for a single package (the scmultiplex package), while it works for all other packages. I can't trace what causes this.

For the active task versions, I see:

On the task management page, it includes the deactivated task versions. But it still sorts wrong:

All other task packages show the correct version as most recent. Any ideas what could be going wrong here?

It seems to only occur once the 0.8.6.dev1 version was added. Is there an issue with how sorting happens in the presence of such dev versions?

Ref #286.

I guess the presence of three dots make the version invalid in semver (ref #286 (comment)), and then coerce is called. But I don't know what is the result of coerce('1.2.3.dev4').

We are not calling coerce in this case. I'm fixing it.

I deployed this at FMI & can confirm that the issue is fixed. Thanks a lot @zonia3000 for the fast turn-around on this one!
