A few fixes, in particular for student follow-up on new repos

[AltGr]

Closes #314, #337

Also cleanup the head logos (one camel is enough :) )

And increase the timeout before warning when grading, as requested by some teachers (it happened too fast in normal situations and was distracting to students)

[erikmd]

BTW, a small request (sorry for the nitpick):

Could you reword (e.g. with rebase -i) your three commit messages so that they follow conventional commits?

E.g.

fix(UI): Increase timeout during grading
fix(UI): Cleanup duplicate, inconsistent camel logos
fix(UI): List exercise status even if the status list isn't initialised; Fix #314

Because since we use release-please, this is the way to ensure commits are listed in the automatically-generated CHANGELOG
(we should definitely document this in CONTRIBUTING.md, did not have to time to do it yet)

Thanks @AltGr! but I believe the type prefix has to be lowercase (fix: or fix(UI):, not Fix:)… so could you please redo a small rebase/force-push?

see this commit message for the comprehensive list of types: 4fd56f7

(admittedly, the spec also allows Pascal-case but I'm unsure it would also be accepted by release-please… and given we'll only have one time to test (at merge time), better safe than sorry :)

Friendly ping @AltGr (for the required rebase -i; but I can also do it if need be; feel free to ask if this helps)

[AltGr]

Ha, sorry and thanks for the rebase, only saw this just now 😬

Hi @AltGr, no worries :-) And thanks a lot for implementing these fixes!
