Bump version to 1.3.11

Bump conan version

Fix issue greg7mdp#117 - segfault when out of memory.

when constructing an object to be inserted throws std::bad_alloc, the slot was mark as used
(even though the object was not properly constructed), so eventually the destructor of a
non-initialized object was called causing a segfault.

Solution: mark the slot used only after the object is successfully constructed.
