Find-Module: Different behavior between local repository and Web server repository.

[LaurentDardenne]

Prerequisites

• Write a descriptive title.
• Make sure you are able to repro it on the latest version
• Search the existing issues.

Steps to reproduce

Created a local repository, copy a prerelease of a package there (example 'Pester 5.5.0-rc1').
Use a remote web server repository), copy a prerelease of a package there (example 'Pester 5.5.0-rc1').

Compare the output of the following command:
Find-Module -Name 'Pester' -Repository

Expected behavior

The behavior must be identical between the two types of repository or 
modify the documentation if this behavior is correct.

Actual behavior

If, for a module, the local repository contains only one package whose version is a prerelease, 
Find-Module returns this module in any case whether the -AllowPrerelease parameter is specified or not.
