hf_mfcsim dump upload bug

Describe the bug After loading the .bin dump file for mifare 1k classic into the flash memory, when the user starts standalone mode, the wrong UUID is generated.

To Reproduce Steps to reproduce the behavior:

1. Load .bin dump file. (eg. mem spiffs upload -s hf-mf-86C6D462-dump.bin -d hf_mfcsim_dump_01.bin )
2. Open standalone mode (see pic 1)
3. Emulate and view results on a reader (reader is showing wrong uuid as well)

Expected behavior Expected uuid to be correct, in the example case to be 86C6D462. I ran the regular emulation mode after loading the bin dump to emulator memory and read it on my reader. The result there was correct as expected, so the file is not the problem.
