UGENE genome aligner can't create a result file twice

Scenario to reproduce:

1. Select {Tools -> NGS data analysis -> Map reads to reference...}

   menu item in the main menu.

2. Select UGENE genome aligner, use input data from the UGENE-1164, unset "use 'best'-mode" option. The output path should be default. Align reads.
   Expected state: there is some result assembly.
3. Remove the result document from the project, remove the result file. Align reads with same parameters again.
   Expected state: there is the same result assembly.
   Current state: a message box appears: "Failed to detect file format..."
