Do not remove the cache under 'Local Podspecs' if the Pod is a local pod

[CrazyFanFan]

The method clean_pod skips the deletion of the cache under 'Local Podspecs' if the Pod is a local pod.

I think you probably should give us an explanation of why you're requesting this change, it's not obvious why this is correct

@orta, thank you for your reply.

In general, the cache of Local Pods under Pods/Local Podspecs is retained, except for the first time when a Pod is switched from a remote Pod to a local Pod, and only in this case is the cache file deleted. The cache file will be retained in subsequent installations.

The reason I discovered this issue is that I did some extra work using the cache files under Pods/Local Podspecs after running pod install, which resulted in some anomalies.

The objectives of this submission are twofold:

1. To address the anomaly I encountered.
2. Unify the behavior of local pods.

Is there any specific design goal for not retaining the cache during the first switch to a local Pod?

When I tried to change the reference of a third-party library, ProgressHUD, from remote to local, I encountered the following error:

Errno::ENOENT - No such file or directory @ rb_sysopen - .../workspace/Pods/Local Podspecs/ProgressHUD.podspec.json

I also noticed that the ProgressHUD.podspec.json file was initially added to the 'Local Podspecs' folder and then removed.

This commit successfully fixes the issue, and I hope it could be merged. Thanks.

Yes, I also encountered this problem, and made local pod code modifications based on this code submission plan, which solved my problem.
