apex:test:run command does not support running tests by providing the class id

[lcampos]

Summary

The official docs and the help output for force:apex:test:run indicates that a user can provide a test's name or id under the -t flag. Providing an Apex test class ID throws the error This class name's value is invalid: 01p5A00000A1aBfQAJ. Provide the name of an Apex class that has test methods.

Steps To Reproduce:

1. Run force:apex:test:run by provide an Apex test ID e.g. sfdx force:apex:test:run -t 01p5A00000A1aBfQAJ
2. Throws an error:

sfdx force:apex:test:run -t 01p5A00000A1aBfQAJ
Listening for streaming state changes...
ERROR running force:apex:test:run:  This class name's value is invalid: 01p5A00000A1aBfQAJ. Provide the name of an Apex class that has test methods.

Expected result

The command should be able to execute the Apex tests when a user provides the Apex test class ID.
