`nimble install -n foo` downloads and builds before checking if foo is already installed, should fail early

[ftsf]

When I attempt to install a package that is already installed nimble should ask me before downloading and building.

nimble v0.13.1 compiled at 2021-05-25 00:49:34

Current behaviour:

nimble install dimscord -n

Seconded This is a bad idea, especially if the lib in question is really big. Then it's just a big waste of time
