proj_activates(".") reopoens the project

[llrs]

I recently created a new project with create_package(path) on the new Rstudio instance I used proj_activate(".") which resulted in opening a new instance of the same project .

Maybe exclude opening the project if it is already opened by Rstudio?

Using usethis2.0.0

Not sure if #905 is related

This is doing exactly what proj_activate() is designed for and as documented:
