tst_Collections: fix Clang -Wuninitialized-const-pointer

Says Clang:
  tst_collections.cpp:661:22: warning: variable 'i' is uninitialized when passed as a const pointer argument here [-Wuninitialized-const-pointer]
    661 |         list.append(&i);
        |                      ^

Fix by initializing the variables. The test does not depend on the
`i`s to be uninitialized, so this will change nothing, except execute
a bit slower and throw no warning.

Amends the start of the public history.

Pick-to: 6.10 6.8 6.5
