Provide dedicated message for obsolete shim case

When a shimmed command can't find usable plugin version, we used to do
several detection then output suggestion to user.

The original message assumes "preset" plugin version is not installed,
which could be false when shimmed command has old `asdf-plugin:` version
written, while not being updated when install newer plugin version.

Here add small `preset_plugin_installed` flag to detect if any
considered "missing" plugin is in fact exist. Print only simple message
for it.

Example output:

    Shimmed command 'yarn' has no matched plugin version
    Check the executable or try install yarn for your preset plugin version
