Error when filtering install tags on install targets with no tag

[bruchar1]

mesonpy\__init__.py", line 860, in _install_plan
    if details['tag'].strip() not in install_tags:
       ^^^^^^^^^^^^^^^^^^^^
AttributeError: 'NoneType' object has no attribute 'strip'

ERROR Backend subprocess exited when trying to invoke build_wheel

It occurs because some targets in intall_plan have null tag.

For an example, it occurs when I try to build wheel for https://github.com/bruchar1/pypkgconf

I wonder whether the strip() call is needed at all. Why would introspection data contain install tags with spurious spaces?

In theory, it is possible to write install_tag: ' silly ' in the meson.build file, but meson strips values passed to --tags argument of install. Therefore, it wouldn't work...
