[Bug]: Inadequate error message for duplicate projects

[eaxreg]

What happened?

When attempting to create a new project, there is an issue with how duplicate projects in the working directory are handled. Currently the IDE is just displaying a generic "failed to create project" message without specific details or assistance. This lack of informative error feedback poses challenges for users trying to identify and rectify the issue efficiently.

What's the expected behavior?

The expected behavior should involve clear error messaging that highlights the presence of a duplicate project.

What version of AndroidIDE you're using?

v2.5.2 (debug builds)
