Jinja sometimes splits in the `Prompted dataset viewer`

Figure out why this happens and open a PR to fix it

Some examples:

[zaidalyafeai]

Seems to be caused by multiple new lines.

[VictorSanh]

yes, that sounds like the right diagnostic
would you like to propose a fix for that @zaidalyafeai ?

Using re.sub(r'\n+', '\n', t) inside show_jinja function seems to resolve the issue. Not sure why {% for candidate in candidate_answers -%} is not in one line, though. Did we have this problem before?

@VictorSanh, If that is ok, I can submit a PR today. Won't be able to work on it later, because I am traveling.

I'd like the rendering to be as faithful as the template (i.e. if there are 3 \n then we should display 3 \n). Would doing a join before calling

promptsource/promptsource/app.py

Line 91 in 415a493

st.write(out, unsafe_allow_html=True)

solve the issue?
