Query: Erratum to the paper "Acylindrical hyperbolicity of groups acting on
  trees"   In our paper arXiv:1310.6289, we stated that acylindrical hyperbolicity of a
group is invariant under commensurability up to finite kernels. Unfortunately,
the proof of this fact contained a gap. The goal of this erratum is to point
out the gap and to correct the statements and proofs of results of
arXiv:1310.6289 and the subsequent paper arXiv:1501.03066 affected by it.
