lib_standard_app: Remove write on BSS variable when app is called in …

…swap mode

Writing these varable is not needed and might collide with
app-exchange BSS. Therefore they should be init only if:
- the app is in standalone mode
- the app is in lib mode, for a SIGN_TRANSACTION command and the params
  from exchange have already been retrieved.

(cherry picked from commit 3c8206b)
