Measure tool does not warn about minimum sizes on objects with a combined symbol

[lpechacek]

Steps to reproduce

1. Create undersized (<0.5 mm²) paved area with a bounding line (501 in Mapper's default symbol set).
2. Active Measure lengths and areas tool.
3. Switch the area to symbol Paved area (501.1).

Actual behaviour

The tool does not warn about the small size in step 2. After step 3, it issues the minimum area size warning.

Expected behaviour

The measure tool should warn when the object size is smaller than any of the assigned symbol areas. That is, in the case of combined symbols, it should examine all area settings in the embedded symbols.
