[SES-205] Fix message clipping

[bemusementpark]

using layout_weight on messageContentView doesn't work well when it is drawn to bitmap as the bitmap will contain a lot of empty space causing it to be cut off. It also pushes the timestamp to the edge.

This PR fixes the issue by

1. removing weight from messageContentView and setting its width to wrap_content
2. wrapping messageInnerLayout with a FrameLayout as the margin_end on profile pic was not respected unless profile && messageInnerContainer were chained. But when it was chained bias on messageInnerLayout was not respected, so views would not appear in the correct places. So this FrameLayout allows us to place child layout at the start or end and allows us to hold the margin here.
