sui move prove is unable to filter modules for verification

[rockbmb]

Steps to Reproduce Issue

1. sui move new mre1
2. Create the following two modules in sources:
   2.1. sources/five.move

   module mre1::five {
       public(friend) fun five(): u256 { 5 }
   
       spec five {
           // this function never aborts
           aborts_if false;
   
           // purposefully wrong!
           ensures result == 4;
       }
   }

   2.2. sources/seven.move

   module mre1::seven {
       public(friend) fun seven(): u256 { 7 }
   
       spec seven {
           // this function never aborts
           aborts_if false;
   
           ensures result == 7;
       }
   }

3. Run (cd mre1; sui move prove)
4. Run (cd mre1; sui move prove --target five)

Expected Result

Recall that sui move prove --help outputs

Options:
  -p, --path <PACKAGE_PATH>                     Path to a package which the command should be run with respect to
  -t, --target <TARGET_FILTER>                  The target filter used to prune the modules to verify. Modules with a name that contains this string will be part of verification
  ...

Meaning that sui move prove --target five should only run the Move Prover for the mre1::five module.

The expected result for both commands, sui move prove and sui move prove --target five is that both find the error with the purposefully incorrect specification of mre1::five::five.

Actual Result

The command sui move prove finds the aforementioned error, while sui move prove --target five fails with

Duplicate package entry for 'mre1'
