[FL-2459, FL-2469]SubGhz: displaying a long name in RAW, launching files from subfolders, bugfix (#1125)
* SubGhz: fix the RAW file is not restored when it is launched from under the folder
* SubGhz: fix does not fit long RAW file name
* SubGhz: fix Read not cleared after file rename
* SubGhz: fix restore default frequency and modulation on output
* SubGhz: fix long name output in RAW
