Use IceCandidateFound event instead of deprecated OnIceCandidate event

[whitphx]

What is the current behavior you want to change?

Current code is using a event OnIceCandidate though the doc says it is deprecated:
https://doc-kurento.readthedocs.io/en/stable/_static/client-jsdoc/module-elements.html#event:OnIceCandidate

What is the new behavior provided by this change?

Use IceCandidateFound event instead as the doc says.

How has this been tested?

I ran the tutorials.

Hi there, thanks for your Pull Request!

A Kurento member needs to verify that this patch is reasonable to test. In case it is, they should write a comment with the phrase test this please. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by Kurento members will still work. Regular contributors can be whitelisted to skip this step.

Browser JS tutorials do not mention usage of OnIceCandidate event, so the tutorial text doesn't need update (contrary to what happens with Node tutorials).

There is a bunch of renames planned for Kurento 7, but for now this is a good first step in updating all client code. Thanks you!

Thank you for acceptance :)

I see, and I'm sorry if it was ahead of the original plan.
I just got confused when reading both the reference and the tutorial, and should have asked in the mailing list first.

Well this PR is in line with the renaming that was on the line, but yes, it's better to first ask because otherwise you might do some work that in the end is not accepted because it conflicts with some other development or planning. But otherwise thanks for your interest in Kurento and your contributions! :)
