Memory Leak

[Robigus92]

After a double rotation of the ClementineSettings there are in heap memory 2 instances more of:

class de.qspool.clementineremote.ui.settings.PreferencesBehaviorPlayer @ 0x12d4b400
class de.qspool.clementineremote.ui.settings.PreferencesBehaviorLibrary @ 0x12d4c400
class de.qspool.clementineremote.ui.settings.PreferencesConnection @ 0x12d4ec00
class de.qspool.clementineremote.ui.settings.PreferencesInformationAbout @ 0x12d4f800
class de.qspool.clementineremote.ui.settings.PreferencesInformationAbout$3 @ 0x12d58340
class de.qspool.clementineremote.ui.settings.PreferencesInformationLicenses$1 @ 0x12d58580
class de.qspool.clementineremote.ui.settings.ClementineSettings$PreferenceListFragment @ 0x12cb5c00
class de.qspool.clementineremote.ui.settings.PreferencesInformationLicenses @ 0x12d51800
class de.qspool.clementineremote.ui.settings.PreferencesInformationLicenses$2 @ 0x12d58640
class de.qspool.clementineremote.ui.settings.ClementineSettings$PreferenceListFragment$1 @ 0x12d3e880
class de.qspool.clementineremote.ui.settings.PreferencesBehaviorDownloads @ 0x12d4d000
class de.qspool.clementineremote.ui.settings.PreferencesBehaviorAdvanced @ 0x12d4dc00

It should not be like this because the rotations return to the same GUI state and the memory should stay in the same state as well. It could be a symptom of a bad management of the onCreate-onDestroy lifecycle.

I have encountered this problem on an Android emulator running 7.1.1 os version.
