…thon's default This fixes a bug where, if a module tries to register a non-default toolchain with the same version as rules_python's default toolchain, an error would occur. This happened because the earlier (non-default) toolchain caused the later (default) toolchain to be entirely skipped, and then no default toolchain would be seen. This most affects intermediary modules that need to register a toolchain, but can't specify a default one. To fix, just skip creating and registering the duplicate toolchain, but still check its default-ness to determine if it's the default toolchain. Fixes bazelbuild#1638
