Fixed PropType warning and show all vote stats in modal

[robert9g]

Fixes #1080 .

Changes:

• moved alt prop's elements from /components/Reactions/ReactionsList.js to /components/UserCard.js because of a PropType warning where alt prop was sent as object but a string type was expected (screenshot below)

• removed the restriction to only show vote info for votes with the value greater than 0.1. This way users can see all the votes information, including the downvotes information (as reported in the 1080)

Screenshot of local (dev-server) PropType warning that comes once you click to show the votes modal:

Hey,
we don't need to refactor UserCard to just fix that warning. We can set PropTypes to anything that makes sense from component's perspective.
To get rid of that warning we can just change PropTypes.bool (which was a mistake I guess) to PropTypes.element.
We shouldn't add any logic to UserCard. It is used in other places (followers/following list, and here vote value is not relevant). It should be as generic as possible.

I understand, thanks for letting me know. I will make the changes you asked.

Followers/following list raises an error it seems if there is just element as PropType, will add string too for the alt prop to avoid this.

Now I do not get any warnings, all logic is back to ReactionsList.js, no extra elements are added to followers/following and all vote info are present in the vote modal including downvotes. Hope it's ok now, let me know when you get a chance.

Yeah, I've meant to replace only bool with element, not everything.
