Error message shown when importing a cmsis project

Hi,

An error message is shown when importing a cmsis project. This error looks like this:

The .rteconfig exists physically on the disk and it is added into the project at import.

The error is reproducible on MCUXpresso IDE 11.7.0 (eclipse 2022-06, cmsis arm version 2.7.0), we also tried an update to eclipse 2022-12, cmsis arm version 2.8.0 and is still reproducible, plus we observed the error on MDK 2020111904.

Steps to reproduce:

1. Create a CMSIS C/C++ Project for a device.
2. Export it to File System.
3. Delete the project from workspace or create a new workspace.
4. Import the project without copy the content in the workspace.

I cannot reproduce the problem in a vanilla Eclipse. However, I suspect that RteProjectUpdater operations get called before the project is fully initialized. There are many participants that trigger the updater, including UI and CDT events.
The plug-ins already implement some measures to postpone the update before C-Project gets initialized, but obviously a not always.

The problem seems to be similar to one described here many years ago:
https://www.eclipse.org/forums/index.php/t/95561/
Since even then there are no hooks nor events in Eclipse that can be used to react on import procedures.

@AncaOprea11 , I have noticed a strange thing in the stack trace: if a mimi.rteconfig would not exist, it the exception would be thrown prior to com.arm.cmsis.pack.project.RteProjectUpdater.collectErrors() call. Could you please have look into .cproject file to check if mimi.rteconfig is specified in .cproject file under <rteConfig> element? Some older projects allowed to use a name that differs from project name.
