Uncaught ReferenceError: fileName is not defined error on HMI during file deleting

[GetmanetsIrina]

Description:
Uncaught ReferenceError: fileName is not defined error on HMI during file deleting

Occurrence: Sometimes (for specific file names)

Preconditions:

1. Start WebHMI and SDL
2. Connect the mobile device
3. Register app from the mobile device
4. Activate the app

Steps to reproduce:

1. The mobile app requests PutFile with a filename like IMG_20210309_172030.jpg
2. The mobile app requests DeleteFile for added file

Expected result:
The file is removed successfully, there are no errors on HMI during BasicCommunication.OnFileRemoved processing

Observed behavior:
