ENHANCEMENT: Do not filter pmpro_has_membership_level on Edit User page

[dparker1005]

Enhancement request is to essentially copy this commit from PMPro Approvals:
strangerstudios/pmpro-approvals@2cef6bc

This will allow Register Helper fields to be shown on Edit User page even if the user has not yet confirmed their email address.
