Bugs I found in the last commit

[Parhamglst]

There were still some bugs with the current code which is not related to my part of the implementation. I don't know if these should exist or not.

• "Create a new Experiment" functionality doesn't add a new experiment after filling all the details.
• "My Experiments" and "Subscribed Experiments" tabs are empty
• Clicking on "My Profile" doesn't do anything
• Clicked on android's back button after creating a new experiment, puts me back into the last page of the process of creating a new experiment
• The description of the the experiment when creating a new experiment should be a multiline EditText, not a single line.
• A LOOOTTTTTT of warnings. Please solve them.
