Fix issue with urlencoded user handles

[ThomasKranitsas]

Fixes #1220

Note that I had to update the start command to webpack-dev-server --history-api-fallback --host 0.0.0.0 --dev --tc --inline --progress --port 3000 --public local.topcoder-dev.com:3000 in order to run the app locally on MacOS..

There is an issue:

1. I have deployed locally and run at local.topcoder.com;
2. I go to http://local.topcoder.com/members/[[iwi]] - it loads the profile, but replaces URL by http://local.topcoder.com/members/%255B%255Biwi%255D%255D/, which is an incorrect URL encoding for [[iwi]] (the correct one is %5B%5Biwi%5D%5D). If I know remove the trailing / and press reload the page, it goes to 404.
3. Similarly http://local.topcoder.com/members/John%20Dethridge, when accessed, replaces URL by http://local.topcoder.com/members/John%2520Dethridge/, which goes to 404, if I remove the trailing /.

This should be polished to ensure that current URL is encoded/decoded correctly.

@birdofpreyru this is a double encoding issue.. I managed to recursively decode the routeParam and get the app working even if the URL is http://local.topcoder-dev.com:3000/members/%252525255B%252525255Biwi%252525255D%252525255D/ ([[iwi]])

I'm trying to prevent the double encoding to avoid such ugly URLs..

I'll push a commit shortly.

@ThomasKranitsas Cool!
Actually, I don't see why we need to replace the URL in such case at all? If we manage to load the profile, when [[iwi]] is inside the URL, why do we need to replace it with URL-encoded one? Also, when there is trailing / no such replacement take place.

@birdofpreyru that's what I'm trying to do actually :)
