Room info retention policy banner does not take exclude pinned messages and only delete files into account in its message.

Description:

When the retention policy for messages are activated, and the option "Only delete files" is selected,
the message at top of channels are correctly showing:

Unpinned files older than 30 days are automatically pruned here (messages stay intact)

However, the retention policy message shown on the group info page, shows:

Messages older than 30 days are automatically pruned here

Steps to reproduce:

1. Go to Administration -> Retention Policy and activate retention policy.
2. In the global policy section, set "True for "applies to ..." for channels, private groups and direct messages, and select 30 days retention policy.
3. Set "True" for "Exclude pinned messages"
4. Set "True" for "Only delete files"
5. Go to a private group and scroll to the top of the messages to view the message. It will read "Unpinned files older than 30 days are automatically pruned here (messages stay intact)"
6. Go to the same private group and click the group info page. The retention message will read
   "Messages older than 30 days are automatically pruned here"

Expected behavior:

The expectation is that the retention policy message/notice should be the same at the top of the message history and on the group/channel info page.

Actual behavior:

The retention policy message/notice on the group/channel info age does not take "exclude pinned messages" and "only delete files" into account when displaying the message.

Start in the group info page and compare its retention-policy notice with the message shown at the top of the message history. Reproduce the configuration using “Exclude pinned messages” and “Only delete files” with a 30-day policy. Done means both notices describe the same retention behavior.
