cordova-plugin-file 6.0.1 "File"

Platforms: iOS 11, iOS 12
Filename examples: 12345.xod, 1212121.xod

Cannot delete some types files in iOS, generates error: FileError code: 5

We retrieve a FileEntry object for the problem files, and can subsequently read the contents, however invoking .remove on the object always fails.

We also experience intermittent success reading these files, which may be a related issue.

We do not experience this problem when using:

cordova-plugin-file 4.3.3 "File"
cordova-plugin-file-transfer 1.6.3 "File Transfer"

Reproduce the failure on iOS 11 or 12 using cordova-plugin-file 6.0.1 and the FileEntry .remove operation, then compare it with version 4.3.3. Check whether the example .xod files can be read and deleted reliably without FileError code 5; the issue does not name source files or tests.
