a8a5dfe6c6 skip e2e encrypted files with empty filename in metadata 
we cannot decrypt a file without a name

for now we will ignore them

we should probably do much more for the user but I fail to see how to
generate errors from e2ee module

ecc588c27a avoid possibly crashing static_cast 
ran
run-clang-tidy-14.py -header-filter='.*' -checks='-*,cppcoreguidelines-pro-type-static-cast-downcast' -fix

this can prevent casting to a type that is unrelated to the real type
and later cause a crash because you go into undefined behavior domain
