bug: when `asdf install` fails, running it again says tool is already installed

[wmcnamee-coreweave]

Describe the Bug

When asdf install <tool> <version> fails, I should be able to run asdf install <tool> <version> again, but it will say: version <version> of <tool> is already installed

Steps to Reproduce

asdf install python 10.0.0
python-build 10.0.0 /Users/<me>/.asdf/installs/python/10.0.0
python-build: definition not found: 10.0.0
error installing version: failed to run install callback: exit status 2

asdf install python 10.0.0
version 10.0.0 of python is already installed

Expected Behaviour

If an install fails, then it should not report that it's already installed, as that's not true. It requires me to run asdf uninstall <tool> <version> first.

This is most often an issue when there's a network failure, or for private tools, not being authenticated to github (as an example).

Actual Behaviour

running asdf install <tool> <version> a second time incorrectly reports that the tool is already installed.
