Cannot import images coming from 2 different groups during the same connection

[Rdornier]

A user is part of 2 different groups A and B on OMERO.

• If an image is imported from group A, the image is imported in QuPath without any issue.
• Then, if we try to import a second image from the group B, it fails with the following error :

15:22:31.722	[project-import11]	ERROR	qupath.ext.omero.core.imageserver.OmeroImageServer	Couldn't create pixel API reader	java.io.IOException: Couldn't find requested image of ID 516335

My guess is that the security context is not updated to access to the correct group (I already had this issue on my side, reported here BIOP/qupath-extension-biop-omero#7).
this.securityContext = new SecurityContext(groupId); to switch group.

So I was able to partially fix this in v0.1.0-rc6. However, there are two limitations:

• Two images of two different groups cannot be read at the same time (see this issue). If an image is open, all images of different groups are now automatically closed.
• If you open an image belonging to group A, then open an image of group B, then open an image of group A, an exception is thrown (see this issue). I wasn't able to find a workaround for that.
