[Password Manager] Disable uploading noisified info about special symbols

We may need to disable the uploading and merge it to late Beta. With this CL, I test that disabling doesn't cause any crashes or other issues. If we don't need to disable uploading, this CL will be reverted.

The uploading was introduced in https://chromium-review.googlesource.com/c/chromium/src/+/1567751.
