'nimble install' doesn't install latest version
Using the `install` command for the `opengl` library with:
```
nimble install opengl
```
always installs version `1.2.2` even though the library has been upgraded to `1.2.3` two months ago!

What controls which version of a library gets downloaded?

I'm on Windows with Nimble v0.11.0 compiled at 2019-09-26.
