Update-KeePassDatabaseConfiguration Fails with Parameter set resolution error

[jkdba]

Opened from #167

Error :
"Update-KeePassDatabaseConfiguration: The parameter set can not be resolved using the specified named parameters."

I had a look at the code.
The error means "PowerShell cannot determine which parameter set it should use".

For example:

• If the command line contains only the -DatabasePath parameter, this can be any parameter set. PowerShell does not know which one to use...
• If the command line contains only the -KeyPath parameter, this can be either the Key or KeyAndMaster parameter set. PowerShell does not know which one to use...

Furthermore, the -DatabasePath parameter is a member of all parameter sets, which makes the thing more difficult to manage and is part of the cause of the problem. It's better to remove all parameter sets from a parameter which is a member of all parameter sets.

By the way, why implementing parameter sets here? A user should be able to update any of those options... I guess just a copy/paste from the New-KeePassDatabaseConfiguration.ps1 script :)

The problem is the same as with the New-KeePassDatabaseConfiguration.ps1 script. Fortunately, when we create a new database configuration we usually use a maximum of parameters. Thus the problem does not necessarily appear for all users with this cmdlet...

Last point: why shouldn't we be able to use a master password, with a file and also a network account? With the desktop application, we can combine it all. However, with the current implementation of parameter sets, this is not possible.

If I accurately understand what you want to achieve, my suggestion is to remove all parameter sets and make a check in the Begin section:

if(
    -not(
        $PSBoundParameters.Keys.GetEnumerator().Where({
            $PSItem -match '^KeyPath$|^UseNetworkAccount$|^UseMasterKey$'
        })
    )
){
    Throw 'You must choose at least one authentication method!'
}

Anyway, thanks a lot for having taken your time to create this module. I use it a lot :)
