Summary: When we try to find the executable module for our target we don't check if we already have an executable module set. This causes that when debugging a program that dlopens another executable, LLDB will take that other executable as the new executable of the target (which causes that future launches of the target will launch the dlopen'd executable instead of the original executable). This just adds a check that we only set the executable when we haven't already found one.
