* 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`.
