Close read-only runs

[YodaEmbedding]

🐛 Bug

Read-only runs give an error when close() is called:

    run.close()
  File "/home/mulhaq/.cache/pypoetry/virtualenvs/compressai-trainer-KZXCvdxM-py3.10/lib/python3.10/site-packages/aim/sdk/run.py", line 695, in close
    self._tracker.sequence_infos.clear()
AttributeError: 'RunTracker' object has no attribute 'sequence_infos'

To reproduce

import aim

def to_hash(run):
    run.close()  # Close each run to prevent "too many open files" error.
    print(run.hash)
    return run.hash

repo = aim.Repo(".")
run_hashes = [to_hash(run) for run in repo.iter_runs()]

Workaround:

import aim

def close_run(self):
    if self._resources is None:
        return
    self._resources.close()

    if not self.read_only:  # FIX
        self._tracker.sequence_infos.clear()

    # de-reference trees and other resources
    del self._resources
    del self._props
    self._resources = None
    self._props = None
    self._cleanup_trees()

def to_hash(run):
    close_run(run)  # Close each run to prevent "too many open files" error.
    print(run.hash)
    return run.hash

repo = aim.Repo(".")
run_hashes = [to_hash(run) for run in repo.iter_runs()]

Expected behavior

No error.
