blissterm: Fix blissterm output
Fix regression which make the output broken.
Plus clean up of unneeded code.
- The new helper to patch prompt-toolkit context was not used
- The initialization was patched to propagate the prompt toolkit app session
- Patch on
getval
was not needed anymore (the whole prompt-toolkit is patched by an app session) - Patch of
"emit"
sounds like not needed anymore (the output is done byBlissServerReplStdout
which already knows everything)
