Layer-crash using latest Avogadro

[ghutchis]

I haven't fully figured this one out, but there's a crash with a variety of code that "replaces" the current molecule. For example, some of the Python commands, but the easiest is:

• draw something
• File => Import => Crystal
• (crash)

bool PluginLayerManager::isActiveLayerEnabled() const
{
  if (m_activeMolecule == nullptr ||
      m_molToInfo[m_activeMolecule]->enable.find(m_name) ==
        m_molToInfo[m_activeMolecule]->enable.end()) {
    return false;
  }

It seems like m_molToInfo[m_activeMolecule] == nullptr. I think the problem is that the new molecule is assigned / uses the copy constructor but that replaces all layer information.
