WebRTC: ice-char can not contain '=' characters for credentials

[Alejandro G. Castro]

We are generating a wrong pass string because we are using base64 random string with padding, and paddings are filled with '=' characters, it is a problem because the sdp parser does not work corrently in this cases and we are not sending good credentials. The parser in the test we have was modified to avoid this issue.

Feels like a word is missing to make these sentences complete
