Fix Hikka search failing due to unclosed response & show toast on remote-removed titles (#3548)

* Fix Hikka search failing due to unclosed response

This closes #3547.

I have also included a precautionary refactor of the `getRead` method
in HikkaApi.kt, which by the looks of it _could_ leak an unclosed
response as well.

The try/catch with awaitSuccess pattern has been used in this same way
in the Bangumi and MangaBaka implementations as well. The benefit here
is that `awaitSuccess()` closes the response on error before throwing
an `HttpException`.

* Show toast on remote-removed list entries
