Steps to reproduce:

`./mach uninstall`

Actual results:

"We're assuming the 'uninstall' command is 'install' and we're executing it for you." happened.

Expected results:

An error telling me uninstall doesn't exist, or actually uninstalling files.

I understand "guessing" feature can be handy, but there are probably commands you don't want to run this way.

This patch explicitly prevents "uninstall" from looking up suggested alternatives. Maybe this should be a list of banned unknown commands?

If you accidentally type `mach uinstall`, it'll still suggest and auto-run `install`, which may or may not be desirable.

Bug 1335620 - Don't assume "uninstall" means "install"

It is a layering violation for mach's dispatch layer to know about the existence of any custom commands. This code is generic and is used by projects like Servo as well. We can't make assumptions about desired behavior.

The proper solution is to somehow declare which commands cannot match other similarly named commands. This could be an argument to @Command decorators. This could be a data structure that is somehow loaded into the mach driver (probably in Either way, specific command names shouldn't be added to python/mach/.
