Moving a post created in-app to a blog on the web doesn't update the app correctly

[AngeloStavrow]

Steps to reproduce

1. On the iOS app, create and publish a new anonymous post
2. On the web, move the anonymous post from step 1 to a blog
3. Tap the refresh button on the iOS app

Expected

The post is updated in the iOS app to show under the blog it was moved to in step 2 above.

Actual

The post remains in the anonymous draft list.

When the completion handler for our fetchUserPosts method runs, there's a block that checks for deleted or remotely-modified posts:

writefreely-swiftui-multiplatform/Shared/Extensions/WriteFreelyModel+APIHandlers.swift

Lines 128 to 141 in 579db0c

	if let managedPost = locallyCachedPosts.first(where: { $0.postId == fetchedPost.postId }) {
	DispatchQueue.main.async {
	managedPost.wasDeletedFromServer = false
	if let fetchedPostUpdatedDate = fetchedPost.updatedDate,
	let localPostUpdatedDate = managedPost.updatedDate {
	managedPost.hasNewerRemoteCopy = fetchedPostUpdatedDate > localPostUpdatedDate
	} else {
	self.currentError = AppError.genericError(
	"Error updating post: could not determine which copy of post is newer."
	)
	}
	postsToDelete.removeAll(where: { $0.postId == fetchedPost.postId })
	}
	} else {

This should also compare the collectionAlias field of the WFAPost object that was fetched from the server against the locally managed object and, if they differ, move it appropriately.
