[Feature Request] Exclude current directory from candidates

[0xC0FFEE]

Thanks for writing this plugin!

Often the following situation happens to me: I want to switch to the folder foo, so I run z foo. However I realize that I'm in the wrong folder (cded into /a/foo, however I wanted to go to /b/foo). In z.lua I could re-run z foo and the current working directory would be excluded from the candidates, so I'd navigate to /b/foo. In zoxide this is not the case, so re-running z foo is basically a nop. Instead I've to run zi foo and select the correct folder.

FWICT there should be no use-case to cd into the current working directory again, so changing this behavior to cd into the next best match should not break any existing use-cases.

Agreed, this should be default behaviour. If a user wants to cd into the same directory (for example, I sometimes need to do this when the directory I'm in has been deleted and recreated by a testing script), they can just use z ..
