pySim/commands: Fix envelope command APDU case after T=1 support

Browse Source 
When we merged I8b56d7804a2b4c392f43f8540e0b6e70001a8970 for T=1
support, the ENVELOPE C-APDU was not adjusted to reflect the correct
case.  ENVELOPE expects a response and hence needs a Le byte present.

This avoids below related message when performing e.g. OTA via SMS

  Warning: received unexpected response data, incorrect APDU-case (3, should be 4, missing Le field?)!
