Editor extraneously reloads files when switching projects

[mrclary]

Problem Description

When switching projects, the Editor seems to close and reopen the documents from the first project, then switches to the new project and loads the documents for the new projects.

What steps reproduce the problem?

1. Open a project with several files
2. Switch to another project
3. Observe the files from first project being closed and reopened, then the new project is loaded with its files.

What is the expected output? What do you see instead?

When switching projects, the first project files should be closed and not reopened.

Thanks for reporting this @mrclary. I can successfully reproduce this bug in 4.3.0.dev0 (also MacOS). I also found another weird behaviour. When I open a project, it not only opens the files of the project but a bunch of files from Spyder's repo. Not sure if it is related.

@dalthviz can you try reproducing this on Windows to see if it also happens there?

@juanis2112 I was able to reproduce this on Windows too:

I noticed this as well, but only when I bootstrap. It does not manifest with the macOS application. This may indicate an issue in bootstrap.py.
