ArgumentOutOfRangeException for small Indexes #162
Description
When running gvfs clone on a small repo, we can get the following exception:
System.ArgumentOutOfRangeException: Must be greater than zero
Parameter name: allocationSize
at GVFS.Virtualization.Projection.GitIndexProjection.ObjectPool`1..ctor(ITracer tracer, Int32 allocationSize, Func`1 objectCreator)
at GVFS.Virtualization.Projection.GitIndexProjection.SortedFolderEntries.InitializePools(ITracer tracer, UInt32 indexEntryCount)
...
This can easily be remedied by initializing the memory pools with a minimum size when the index is small.
