Misc UI improvements for TCA:
- going back and forth between consent question, bridge selection, error page used to give incoherent selections. now this is fixed.
- if you select "easy" with no custom bridge, and connection fails, TCA falls back to default bridges. When doing so, now it implements this:
- fix a small (but important) bug that make switching from direct connection to bridges through the error page not working.
