Re-enable old fee extensions in sandbox (#2939)

Now that we've passed the RST testing (or at least the EPP portion of
it) we are no longer bound by the restriction to only use the fee
extension version 1.0 on sandbox.

For now, in order to avoid changing prod behavior, this does not enable
advertisement of the fee extension version 1.0 in production. We can
change this at any point in the future.
