fix #3054

[AmandaBirmingham]

Improves the display of prep info in the study page side-bar as specified in #3054, adding for each prep the total number of samples as well as the creation and modification date, which artifacts have been produced, and whether it is ready for submission. Displays preps in ascending order by creation date. See example below.

Coverage increased (+0.01%) to 91.16% when pulling b00bfa6 on AmandaBirmingham:dev into 4e15351 on qiita-spots:dev.

Looks great, thank you for putting together, some minor suggestions, see below:

• if the prep has been submitted, no need to show that is OK to submit
• the comma (,) between the number of samples and the samples submitted has a space, can you remove it?
• I don't think we need the word Progress in the progress line, perhaps worth removing?

[AmandaBirmingham]

@antgonza Thank you! I will remove the word "Progress" and the space before the comma, as you described. I need a bit more guidance to know when to put in the "ok to submit" entry: should I leave it off if the is_submitted_to_ebi property of the prep is True? Or?

[antgonza]

Thank you; BTW there are also spaces after the commas in the Progress elements.

That's a good question, I think we should remove the "OK to submit" for now, to avoid confusion, and add once we have this: #2721 ready.

[AmandaBirmingham]

@antgonza Ok, can do. How does this look?

(I know it kinda looks like there are still spaces after the green checkmarks, but there really aren't :)

[antgonza]

Looks great, could you push to your branch so the tests run and, if everything passes, I can merge? Thank you.

[AmandaBirmingham]

@antgonza should be ready for you!

Thank you so much!
