Table(list_of_dicts) does not work as expected for quantities

See original GitHub issue

Description

Giving Table a list of dicts with quantities results in dtype object with single quantities in each row / column.

Expected behavior

Detect the quantities and create a column that has dtype float and a unit attached.

Actual behavior

See description

Steps to Reproduce

In [1]: from astropy.table import Table

In [2]: import astropy.units as u

In [3]: data = [{'x': 5 * u.m, 'y': 0 * u.m}, {'x': 10 * u.m, 'y': 3 * u.m}]

In [4]: Table(data)
Out[4]: 
<Table length=2>
  x      y   
object object
------ ------
 5.0 m  0.0 m
