Mixed language in report notification emails

[Kirby]

Affected version

2.3.0 Beta 1

Steps to reproduce

1. Create an additional language: Moderator Language
2. Create a moderator, set its language to Moderator Language and enable option Receive email when content is reported
3. Translate phrases report_create_body_html, view_this_report, the_following_reason_was_given, reported_content and post_in_thread_x so their text is distinguishable from the default
4. Create a post
5. Report that post using a language other than Moderator Language (=Reporter Language)

Expected Result
All non user-generated text in the email is in Moderator Language

Actual Result
Phrase post_in_thread_x is rendered in Reporter Language

Why does this happen?

The email template is rendered in Moderator Language but the report title is taken from the report entity via cached getter getTitle which calls getContentTitle on the handler class - this method then uses phrase post_in_thread_x.

Suggested Fix
Use {{ $report.getTitle() }} instead of {$report.title} to bypass getter cache.
