[CIS-1104] Fix message list dismissing in modal when scrolling

[nuno-vieira]

Description of the pull request

Problem:

Currently, we are using an inverted UITableView for the message list. This causes an issue when the message list is presented in a modal because when the tableview is reaching the bottom, the modal actually thinks it is reaching the top and starts dismissing the modal.

More details here: #1307

Solution:

In order to fix this, the most simple workaround, for now, is to disable the dismissing of the modal when the table view is scrolling. The con with this workaround is that the user can't dismiss the modal while scrolling to the top. The user needs to dismiss the modal from the navigation bar or other place. Please watch the example below:
