Fix voice session destroyed after bot moved

[ferrenza]

When the bot moves channels, the player was being destroyed because the disconnect wait did not account for the brief period between disconnect and reconnect. This commit modifies _disconnected_wait to wait for the _reconnecting event and then verifies the current voice state via guild.me.voice.channel If a valid channel is detected, the connection is restored without calling _destroy() This prevents accidental player deletion during channel moves.

Description

This PR fixes an issue where the player was inadvertently destroyed when the bot moved from one voice channel to another. By waiting for _reconnecting and checking guild.me.voice.channel, we ensure that a valid reconnect occurs before deciding whether to destroy the player. This prevents the brief disconnect period from prematurely removing the player's session during channel moves.
