Bug description

The "Read More" functionality for relatively long messages (1000-2046 characters in length) in the Android client is incorrect and always truncates the last 2 characters of long messages, which makes it quite useless. It appears to trigger for texts containing >1000 characters. Starting at 2046 character message length, the truncation is performed differently and always shows the first 2046 characters only, at which point this feature makes sense again.
This means when I for instance paste a text with 1500 characters, then Signal Android will show the first 1498 characters of the message followed by "... Read More".
This means that a) long messages (of 1000-2046 characters in length) are not actually significantly shortened, and b) that the feature just makes long messages harder to read because you need to interact with the message to reveal the last 2 characters.

For comparison, on Desktop (Linux) the feature seems to work like this: for any message exceeding 900 characters, the first 800 (!) characters + "... Read More" are displayed. This makes sense! The Android behavior on the other hand does not.

Reproduction:

1. Open Signal Android
2. Open any conversation
3. Write a text to someone that is >1000 and <2046 characters long (e.g. the one attached below)
4. Send the text

Expected: You see e.g. the first 1000 or 900 characters, and the rest is hidden behind "... Read More", meaning if you click "Read More", at least several words of text appear.
Actual: You see n-2 characters followed by "... Read more", and if you click it, you see only two additional characters.

Example text, this one is 1499 characters long:
