[HOTFIX] Fix uninitialized warning in send_receiver_test.cpp

[LeonhardFS]

Hey, thanks for sharing the code online!

Wanted to try it out, and everything works very smoothly except for a warning that leads to an error given the -Werror setting. Submitting a quick one-liner fix here.

Error log:

.../AnyBlob/test/unit/network/send_receiver_test.cpp: In function ‘void anyblob::network::test::C_A_T_C_H_T_E_S_T_0()’:
.../AnyBlob/test/unit/network/send_receiver_test.cpp:60:37: error: ‘skip’ may be used uninitialized in this function [-Werror=maybe-uninitialized]

My platform:

Ubuntu 22.04.03
CMake 3.22.1 (also tried with 3.31)
GCC 11.4

Let me know if this acceptable or you'd like me to make additional changes!

Thanks, Leonhard! This is by now already resolved.
