Avoid a list assignment

That list wasn't used elsewhere
Factor out the conversion template for date and timestamp
Make 2 my()s into 1
Add cast_for_data_conversion() to use when SQL needs to compare dissimilar types

When we join on two columns that have different types, this method figures out
what function to use to convert to a type we can comare with.  This current
implementation for Oracle only works when one column is a Text type, and
converts the other column using to_char
Add left/right coercion info for joins

For each join, add information about how to coerce each side of the
join condition to the other side, so the database can compare them.
Use the coercion information to build the where clause
Reverse a previous commit where we made UR::Value::Number isa Text

Now that we can do coercions in SQL, this isn't necessary anymore
whitespace
prime the class_alias cache with the source class' table name

This is required to get GenomeInstrumentData/Command/Import/Fastq.t working
refactor intersect_lists() into UR::Util
test case for joining text-type columns with non-text columns in Oracle
remove empty 'has' section from the test
