Limit max lines for transaction list item path and host

[vbuberen]

📄 Context

As reported in #310 some users have long queries and one item of transaction item might occupy a lot of screen space. To address this issue I suggest to limit path lines to 4 and host lines to 2. It should be enough for preview and shouldn't be critical, because user can always open the transaction to see the full path and host.
Also found out that Chucker missed ellipsize property for Toolbar title, which was limited by 2 lines already.

Closes #310

📝 Changes

• Limited maxLines for transactions list item path to 4 lines.
• Added ellipsize=end to list items and to Toolbar title
